1 Claim. (Cl. 16-169) This invention relates to hinges or butts of thetype having a pair of leaves with interfitting knuckles provided withaligned bores, a removable pin extending downwardly through the knucklesfor pvotally connecting the leaves together, and a tip or closure memberpermanently secured to the lower end of the bottommost knuckle andcovering the bore thereof.

In a hinge or butt of this type, the pin or pintle, While permittingrelative pivotal movement of the leaves, sometimes becornes stuck in theknuckles. In some instances, hinges of this sort are provided with meansfor preventing the pins from gradually working up from their seatedpositions upon repeated operations of the hinge. It is usually thecustom to remove the pin by applying a tool to the head of the pin andthen exert an upward force on the tool. For example, attempts may bemade to remove the pin from the knuckles by pulling the pin upwarclly bymeans of a par of pliers applied to the head or upper end of the pin; orby driving the pin upwardly by applying the upper end of an inclinedblade or tool to a generally downwardly facing portion of the head andstriking the lower end of the tool with a hammer; or by driving the edgeof a tool between the head and the upper surface of the uppermostknuckle and then using the tool as a pry or lever. In any event, withhinges of this sort, difficulty has been experienced in removing the pinwhen it is desired to disassemble the leaves, and in the operation ofremoving the pin, damage to and marring of the head thereof and theadjacent members to which the hinge leaves are connected result.

The object of the present invention is to provide un improvedarrangement whereby the pin may be quickly, easily, and convenientlydriven upwardly from its operative or seated position without anylikelihood, or in faet possibility, of da.rnaging any portion of thehinge or -any portions of the members to which the hinge leaves areconnected.

Other objects Will be in part obvious and in part pointed out more indetail hereinafter.

In the drawing:

Fig. 1 is a side view of an open hinge, the two lower knuckles bengillustrated in longitudinal cross seetion so as to reveal the internalconstruction, and

Fig. 2 is an elevational view of the bottom or lower edge of the hinge.

Referring to the drawing in detail, A and B are ordinary hinge leavesformed of sheet metal and respectvely hav ing rolled knuckles 11 and 12.The knuckles of the two leaves are interfitted so that the bores thereofare in aligned relation. The pin is designated by the letter C. Il; has,at its upper end, a head 13 the under surface of which seats against theupper end of the uppermost knuckle 12. Driven in, or otherwisepermanently secured to, the lower end of the bottom knuckle 12 s a tip Dwhich serves the usual purpose of giving a finished and pleasingappearance to the hinge. In the present illustrative disclosure, thebottom tip member is shown as having a stud portion snugly fitted in thebore of the lowermost knuckle and a head portion engaging against thelower edge of the knuckle.

If desired, -any sutable means may be provided for preventing the pin Cfrom gradually working up from its seated position. Por illustrativepurposes, I have shown here this means as comprising a spring ring Epositioned in a groove in the pin and arranged to engage a downwardlyand outwardly flared portion 14 of the lower end of the bore of theuppermost knuckle 12. An arrange ment of this sort is shown in the MorsePatent No. 2,154,860, issued April 18, 1939.

With the construction so far described, it is apparent that if it Wereattempted, as has heretofore been necessary, to withdraw the pin fromthe knuckles by engaging the head of the pin with a tool, as by a pairof pliers and pulling upwardly or by means of a tool applied against theedge of the head and driving or prying upwardly, the aforementioneddisadvantages and dificulties would be experienced. In accordance withthe present invention and in order to avoid these and other diflicultiesand disadvantages, the tip D is provided with a small central bore oraperture 15 arranged to permit the insertion of a nail 16 or the likeinto the tip and the engagement of the upper end of the nail against thebottom end of the pin C. The nail having been so inse1ted, the pin maybe forced up sufliciently to permit the head thereof to be convenientlygripped by the fingers by tapping the lower end or the head of the nail.It will thus be observed that the pin may be quickly, easily, andconveniently raised from its seat and removed without any danger ofinjuring the pin, marring its head, or marring or damaging the door jambor door or the finish on the knuckleg. At the same time the aperture orbore 15 in the tip D is of relatively small diameter so that the finishor pleas ing appearance given to the hinge by the tip is in no waydetracted from.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting senso.

It is also to be understood that the language used in the followingclairn is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.

The present application is a continuation of my copending application,Serial No. 167,873, filed June 13, 1950, now abandoned.

I claim:

In a hinge of the type compris-ing a pair of hinge leaves having aplurality of integral knuckles along one edge of each of the leaves,said knuckles being in interfitting relation and having aligned bores, aremovable pintle engaged in said bores provided with a button-like headhaving a single downwardly facing surface in the form of a flat baseengaging against the upper end of the uppermost knuckle andsubstantially covered by said knuckle, and means between the pintle andone of said knuckles for impeding removal of the pintle; a closuremember permanently secured to the lower end of the bottommost knucklehaving a stem fixed in the bore of the lowermost knuckle and abutton-like head having a configuration similar to that of the head ofsaid pintle including a single upwardly faeing surface in the form of aflat base engaging against the lower end of the lowermost knuckle, saidclosure member being provided with an elongated axial throughbore ofsmaller diameter than the pintle extending through the head and stem toreceive and slidably support a nail or other pintle knockout tool ofsmaller bora walls.
